Description
Technical Field
[0001] The utility model relates to the technical field of polyethylene pipe production, in particular to a spray cooling device for polyethylene pipe production. Background Technique
[0002] The thermoplastic resin formed by the polymerization reaction of ethylene, namely polyethylene, and its copolymer with a small amount of α-olefin are widely used in industry. Polyethylene materials are favored in the manufacture of polyethylene pipes due to their odorless, non-toxic, waxy touch, excellent low-temperature resistance, and excellent chemical stability, which can resist the erosion of most acids and alkalis. These pipes meet a wide range of usage requirements with their excellent physical and chemical properties.
[0003] In the production process of polyethylene pipes, in order to improve production efficiency and precisely control the outer dimensions of the pipes, the use of a cooling device is crucial. It not only accelerates the cooling process of the pipes but also ensures the stability of product quality. The wide application of polyethylene materials in the field of industrial chemicals has led to a pipe market that includes not only polyethylene pipes but also polyvinyl chloride plastic pipes. Although the application scale of polyethylene pressure pipes was much smaller than that of polyvinyl chloride in the early stage of the development of plastic pipes, with technological progress, high-performance and high-strength polyethylene pipes have gradually become the market mainstream.
[0004] The existing patent (application number: 202320879964.2) discloses a cooling device designed specifically for polyethylene pipes. The device includes a circular pipe and a drainage mechanism thereon. The drainage mechanism consists of a bottom pipe, a merging pipe, and an annular groove. The annular groove is ingeniously arranged inside the circular pipe, and three bottom pipes are firmly connected to the bottom of the circular pipe and are closely connected to the merging pipe. This design enables hot sewage to be cooled by the drainage mechanism before flowing through the polyethylene pipe, effectively protecting the inner wall of the pipe and extending its service life.
[0005] However, the inventor found during the practical process that the function of this cooling device is relatively single. Although it can recycle sewage for re-cooling spray, the cooling efficiency of the single cold water spray method is limited and its practicability is not strong. In order to improve the cooling effect, it is often necessary to increase the amount of cold water sprayed, which undoubtedly increases the consumption of cold water. Therefore, how to reduce cold water consumption while maintaining efficient cooling has become an urgent problem to be solved. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model
